本文研究了用青铜加工的商用多芯Nb/sub 3/Sn线材在残余应变状态下的T/sub c/、B/sub c 2/和J/sub c/。发现应变下B/sub c ~ 2/的温度关系在T=0附近服从（1-（2/3）（pi T/1.75T/sub c/）/sup ~ 2/），在T/sub c/附近服从（1-T/T/sub c/）。在商用Nb/sub 3/Sn线材中证实了整体钉扎力F/sub p/=J/sub c/*B的温度标度律的建立。
The T/sub c/, B/sub c2/, and J/sub c/ were investigated for superconductors in a residual strain state for bronze processed commercial multifilamentary Nb/sub 3/Sn wires. It was found that the temperature dependence of B/sub c2/ under strain obeys (1-(2/3)( pi T/1.75T/sub c/)/sup 2/) near T=0 and (1-T/T/sub c/) near T/sub c/. The establishment of the temperature scaling law of a global pinning force F/sub p/=J/sub c/*B was confirmed in commercial Nb/sub 3/Sn wires.
